Stop & Start
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The
engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.


Operation


Going into engine STOP mode

With the electronic gearbox system,
for your comfort during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as
braking, power steering, for example.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. The "ECO"
warning lamp comes
on in the instrument panel and the
engine goes into standby:


- with a manual gearbox
, at speeds below
12 mph (20 km/h), when you put the gear
lever into neutral and release the clutch
pedal,

- with the 6-speed electronic gearbox
system
, at a speed below 5 mph (8 km/h),
when you press the brake pedal or put the
gear lever into position N
.
If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets
itself to zero every time the ignition
is switched on with the key. STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine star t
using the key,

- the electric parking brake is applied or
being applied,

- the engine is needed to maintain a
comfor table temperature in the passenger
compartment,

- demisting is active,

- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.


Special cases: STOP mode
unavailable
In this case, the "ECO"
warning lamp
flashes for a few seconds, then goes
off.

This operation is per fectly normal.

Changing the coolant

The coolant does not have to be changed.


Coolant specifi cation

The coolant must conform to the
manufacturer's recommendations.



Coolant level

The coolant level should be close
to the "MA X" mark but should never
exceed it.
When the engine is warm, the
temperature of the coolant is regulated by the
fan. This can operate with the ignition off.

On vehicles which are fitted with a par ticle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the engine is cold.
In addition, as the cooling system is pressurised,
wait at least one hour after switching off the engine
before carrying out any work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove
the cap and top up the level.

Power steering fluid level

The power steering fluid level should
be close to the "MA X" mark. Unscrew
the cap, with the engine cold,
to check the level. To check the level or top up the
fluid on vehicle fitted with headlamp
washers, immobilise the vehicle and
switch of the engine.
